To ALL WHoM IT MAY CONCERM' l Be it known that I, WILLIAM INMAN, of Middletown, in the county of Orange, and State of New York, have vinvented a new and improved Means for Securing Jig or Muley-Saws to their Slides; and I do hereby declarethat the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this"spiecic'ation;`

This invention relates to a new and improved means for secnringjig or muley-saws to their slides, whereby the saws may be very readily secured to and detached from their slides, and, when secured to them, firmly held, without the possibility of becoming detached. In the accompanying she/et of drawings* Figure 1 is a vertical section of'my invention, taken in the line x rd, hg. 2.

'Figure 2, a plan or top view cf the same.

' Similar letters of reference indicate corresponding parts. Y

A represents a jig or muleysaw, of usual construction, and B B represent two clamps, by which the ends ofthe saw are secured to their slides. These clamps are composed each of a yoke or frame, in which unV eccentric, b, is fitted. These eceentrics have each an arm or lever, e, extending from them, and the eccentries are parallel with' one side, a, of the yokes or frames, as shown clearly in g. 2, a space being allowed between the eecentries and the sides a of the yokes or frames to receive the ends of the saw, when the eccentrics are so turned or adjusted that their prominent sides will not be opposite the sides a. When the ends of the saw are fitted in these spaces between the sides a and the eccentrics b, the latter, by means of the arms or levers c, are turned, so as to clamp the saw, and the latter will be firmly held and secured to the slides, one of`- which isshown in red in tig. 1. The yokes or frames have bolts, e, extending from them, one from each, and these'bolts pass through theslides, shown in red, fig. 2, and have nuts,f, on their outer ends, (see fig. 2.) i'

By this arrangement it will be seen that the saw inay be secured toand detached from its slides with the greatest facility, and without the possibility of becoming casually detach-edwhen secured in the clamps, for the strain to which the saw is subjected in its operation only serves to keep it more tightly bound in the clamps.

' I claim as new, and desire to secure by Letters Patent- The securing ofjig or muleysaws to their slides by means of clamps B, composed each of a yoke or frame, with an eccentric fitted therein and attached to the saw-slides, substantially as shown and described.
